Description
The BL121DT is a protocol converter with Ethernet ports and RS-232/485 serial ports. Beilai BL120DT protocol converter supports DLT645, IEC104 protocols converting to OPC UA protocols. This protocol gateway is widely used with power industry applications.
Key Features
Intelligent Bidirectional Protocol Conversion
- Downlink Support: DL/T645 (Chinese standard meter protocol), IEC104 (power telecontrol protocol)
- Uplink Support: OPC UA (Industry 4.0 standard protocol)
- Seamless integration between legacy devices and modern cloud platforms to eliminate data silos
High-Efficiency Data Acquisition
- Simultaneous connection for 10 devices with 512 data points collection
- Dual-channel RS485/RS232 serial ports supporting Modbus RTU/TCP transparent transmission
Industrial-Grade Reliability Design
- Wide-Range Power Input: DC 9-36V with reverse-connection protection
- Enhanced Protection: ESD protection: ±8kV (air discharge)/±6kV (contact discharge)
- Hardware watchdog + software monitoring for 24/7 stable operation
Typical Applications
Smart Grid: Traditional substations collects relay protection device data through IEC104 to the power grid platform.
Smart Building: The power distribution room collects meter data through DL/T645 to the OPC UA platform to monitor power load in real time
